[texts]High-Q X-Band and K-Band Micromachined Spiral Inductors for Use in Si-Based ICs - Lu, Liang-Hung
A micromachined structure with reduced parasitics is proposed to enhance the resonant frequency and the quality factor (Q) of a spiral inductor. Inductors with various etch depths have been fabricated on a high resistivity Si substrate. Two-port S-parameters measurement is taken to characterize the performance of the inductors. With an etch depth of 20 micron, a fabricated 1.8 nH spiral inductor achieves a maximum resonant frequency of 25.6 GHz and a maximum Q of 20.2 at 14.5 GHz...

[texts]Interaction between an upstream facing wall jet and a supersonic stream - Piva, R
The flow field resulting from the interaction of an upstream facing wall jet with a supersonic counterflowing stream has been investigated. A flow field model and the main parameters governing the phenomena were determined from quantitative and qualitative experimental observations. Experimental results for different ranges of the main parameters are presented. A theoretical analysis was performed to describe the flow field in the mixing region between the two counterflowing streams...

[texts]Characterization and photocatalytic activity of nanostructured indium tin oxide thin-film electrode for azo-dye degradation
Photocatalytically active indium tin oxide thin film electrodes were prepared by electron beam evaporation technique onto a glass substrate having thickness 120 nm. Degradation of reactive dye yellow direct 42 has been performed using photoeletrocatalysis. A biased potential is applied across indium tin oxide photoelectrode illuminated by UV light. The best experimental conditions were found to be dye concentration 1.0Ã10â5 mol Lâ1, pH 5.25 and 0.5 mol Lâ1 NaCl as supporting electrolyte when...

[texts]Room Temperature and Elevated Temperature Composite Sandwich Joint Testing - Walker, Sandra P
Testing of composite sandwich joint elements has been completed to verify the strength capacity of joints designed to carry specified running loads representative of a high speed civil transport wing. Static tension testing at both room and an elevated temperature of 350 F and fatigue testing at room temperature were conducted to determine strength capacity, fatigue life, and failure modes. Static tension test results yielded failure loads above the design loads for the room temperature tests, c...

[texts]Challenging the Future - Journey to Excellence. Aeropropulsion strategic plan for the 1990's - NON
Over the past several months, the Lewis Aeropropulsion Management Council (AMC) has conducted a critical assessment of its strategic plan. This assessment clearly indicated a need for change, both in the aeropropulsion program emphasis and in the approach to carrying out that program. Customers sent a strong message that the program must improve the timeliness of research and technology products and services and must work more closely with them to develop and transfer new technology...
